摘要：
A CMOS-based linearly tunable transconductor is proposed in this paper. The realization technique is achieved by using a fully differential transconductor and a current variable gain stage, for a power supply of +/- 1.5V. Its transconductance gain can be linearly tuned by an external bias current for more than 4 decades. The transconductor cell is designed in 0.5 mu m AMIS technology. The performance of the proposed circuit is discussed and confirmed through PSPICE simulation results.
